Long-term effect of laser subepithelial keratomileusis in the treatment of super-high myopia.

Objective To evaluate the long-term effect of laser subepithelial keratomileusis(LASEK) for super-high myopia(≥-10.00 D).Methods Eighty-three cases (151 eyes)of super-high myopia who had been treated with LASEK in our hospital from December 2003 to January 2006 were followed up from 25 to 49 months(mean 35.34±6.45 months).Before the operations,visual acuity,the best corrected visual acuity,and diopter was 0.01-0.1(mean 0.053±0.025),0.5-1.2(mean 0.098±0.145),and-10.00～-14.50D(mean-11.01±1.19D),respectively.Results After the operations,visual acuity was 0.2-1.5(mean 1.01±0.26),and was 1.0 or better in 120 eyes(79.47%),and 0.6 or better in 142 eyes(94.04%).In addition,5 eyes had a 0.5-level Haze and 1 eye had a 1-level Haze.Conclusion LASEK is an effective and good method to correct super-high myopia and is stable and safe with satisfactory visual acuity and less complication.
